Target Details CTLA4

The lymphocyte surface antigen CD152, also known as CTLA-4, is related to the co-stimulatory molecule CD28, and both molecules share common B7 family counter-receptors. However CD152 is thought to be a negative regulator of T cell activation and may play a role in apoptotic control of T cells. CD152 exists as a 69 kDa homodimer, and is relatively conserved among humans, mice and chickens.
